Yeah I think thats the cover but I didnt realise it still had a hole in it. I knew its not water tight, I can just barely see mine next to the crossmember & its had crap flushing out.

That was the only thing I could think of why I dont get ANY clutch slip even when repeatedly using the clutch while its under. Even when it had been submersed for ~5min I had to depress the clutch to drive out & still no slip
